This is a report of a research project involving, in Phase I, the skid resistance of asphaltic concrete overlays. Phase II is a report of a pilot study set up in order to determine the best way to perform a skid resistance inventory of the highway network in Louisiana.
Phase I was conducted from August 1969 to August 1974 and included the skid testing of 19 dense-graded, asphaltic concrete overlays with hard rock (stream deposited, chert gravel) as the coarse aggregate. The skidding was conducted every six months for the five-year period. Also included herein are the results of a study of the pavement texture by means of the stereo-photographic method.
Phase II established that a skid resistance inventory could be run using the ground rules set by the Department's Traffic and Planning Section. Reporting would be in a graphical form, and the basic unit of the highway inventory would be the control unit (C. U.).
The Asphalt Pavement Analyzer (APA) device was used to characterize the impacts of various mix factors on the development of permanent deformation den...
In 1989, two pavement striping tape materials were placed on two new asphalt pavements. A two-year performance evaluation of the materials has been co...
